I've read thru the forums here as well as other sites concerning the six-blink code. I've had this PF100 for three seasons now - it is used and one of the first models per the serial no. (12##). Have not had any trouble with it until now. Did the last major cleaning of everything on 10/31. Around 11/10, it went out with six blink status. Burn pot was empty. Fired it back up manually (as I always do), and noticed a pattern of about every 48 hours or so, it would go out with six blink status. Now it's down to going out every couple of hours. My wife just emailed and said she had to restart it - I had to restart about four hours ago.
I've gone back thru everything - emptied hopper and watched auger cycle - everything looks fine there - pellets dropping as they should. Pulled combustion motor and cleaned fins again even though they weren't bad. Also vacuumed out that area and up into flue which I cleaned all the way to the chimney on 10/31. Grate holes are all open. I've adjusted feed rate to try to compensate - I used to always run it just under three for our pellets. Have tried it up to almost five - and it still goes out.
It acts like the low-burn process isn't working - I think that's when it goes out. Thinking back to pellet stoves I've had (been burning pellets for 15+ years now), I sometimes had to replace one of the blower motors even though they didn't sound like they were slowing down - but new motor always made the difference. Wondering if the same might apply to the combustion motor. Auger seems to be fine - can hear pellets dropping on every cycle. Or maybe circuit board is bad? I've basically eliminated everything but the draft per the bolt in upper left when you open the door - and I find nothing in manual for adjusting that, or even if it is adjustable. I've adjusted the little white dial on the circuit board - that's done nothing and it always has been all the way open (CW).
It's not a pellet issue - we make them here with waste from our major product line - three other family members also use the pellets - nobody else is having issues with it, and I've not seen anything wrong with length, snap, etc.
Any other thoughts?
